Construction
Site and Phased Development Control Networks
Marshall
Lancaster & Associates, Inc. also
provides control networks for phased, large
scale engineering, design and construction
projects. Control networks can be developed
to satisfy the needs of a construction company's
internal engineering department. We have
extensive experience calculating and setting
structural building control for unusually
large or complex building designs. Construction
companies also utilize our field control,
data analysis, and mapped reports to satisfy
project specifications or as verification
of control set by other firms.
Aerial
Photogrammetry Ground Control Networks

Lancaster & Associates, Inc. utilizes
a combination of Global Positioning Systems
and Robotic Total Stations to construct
horizontal and vertical control networks
for aerial photography.
Aerial
target specifications and location is coordinated
with the photogrammetrist. Horizontal and
vertical values of aerial targets are provided
to photogrammetric companies in a variety
of digital formats.
Random
cross section check shots taken on the ground
at the time of control are then used to
evaluate contour mapping developed by the
photogrammetrist.

Lancaster & Associates, Inc. can
implement strategies to monitor critical
structures. We provide mapping and reports
depicting quantities for excavation projects
or movement of dams, levees, retaining walls,
